Jamie Arthur (born 17 December 1979 in Aberdeen) is a boxer from Cwmbran, Wales, who won the gold medal in the men's lightweight division at the 2002 Commonwealth Games in Manchester, United Kingdom. Arthur turned professional in 2003, and since then has had some success, winning the Welsh super featherweight title in 2008. In March 2010 he fought for the British featherweight title, losing to Martin Lindsay by unanimous decision. In May 2010 he competed in the Prizefighter series at super bantamweight, beating Robbie Turley in his quarter final before losing to the undefeated Ricky Owen in the semi final.
On 16 October 2010 he fought Kris Hughes for the vacant Commonwealth Super-bantamweight title winning on points decision. His reign as champion was short-lived as he lost in his first defence to Jason Booth in February 2011. In 2012 he challenged Scott Quigg for the British Super-bantamweight belt, and despite knocking the unbeaten Quigg down in the fourth Arthur was stopped in the eighth round.
